About This Product
Each fork is held by its stem and one prong struck gently with a rubber hammer or suitable striker, and the vibrating fork is brought near the ear without touching it. Placing the stem on a resonance box or sounding surface raises the sound level. Comparing the tones of different forks lets students hear the pitch difference and relate it to frequency.
Frequently Asked Questions
